FIA full steam ahead on liquid hydrogen
The FIA will concentrate its sustainable powertrain efforts on the promotion of hydrogen stored in liquid form.
After the first FIA World Motor Sport Council meeting of the year, the global motorsport body gave further details on its preferred strategy of implementing hydrogen technology as it tries to reduce motorsport’s carbon emissions.
It is looking at liquid hydrogen (LH2) because of the lower volume and weight of the storage tank vs hydrogen stored as compressed gas. The FIA deems LH2 storage to be ‘better suited to the demanding environment of motorsport competitions, where optimisation is key.’
Liquid and compressed gas are the two main types of mobile hydrogen storage, but there is no global consensus on which is best. Hydrogen has a low volumetric energy density, so it needs to be liquefied or compressed to be stored in a
